Nie Tian laughed embarrassedly, and the mysterious man directly skipped the opening of the scriptures and said, "The supreme and profound subtle method, this is to praise the supreme and profound teachings of the Dharma, and the supreme means that there is no kind of learning in the world that can surpass the teachings of Buddhism."

Hundreds of thousands of calamities are encountered, which means that the opportunity to be a human being is rare, and the Dharma smells bad, and after this life, it is difficult to guarantee whether you can be a human being again in the next life. It all depends on what kind of karma we have created, and if we create negative karma, we can easily enter the realm of beasts, hungry ghosts, and hells, and we will not have the opportunity to listen to the Dharma and attain liberation.

Since it is rare to be a human being and I have done it, and I have heard of the Dharma now, from now on I must pursue and study the Dharma well, and practice and practice it in accordance with the Buddha's teachings.

The only wish of a Buddhist student to receive the Dharma is to thoroughly understand the true teachings of the Buddha, to believe, understand, act, and prove, and to enter the Buddha's path.

As it is, it is the inherent nature of each human being. In other words, everyone has Buddha nature, and as long as they understand the Buddha's principles, they can become Buddhas and get rid of the six realms of reincarnation! ”

Nie Tian didn't expect a poem to open the scriptures, so much knowledge, and exclaimed: "Sir, the knowledge is profound, I didn't expect to have a study of Buddhism, then sir, do you believe in ghosts, gods, and Buddhas?"

Do you think there is really reincarnation in the world? ”

The mysterious man suddenly paused, as if he was thinking seriously, and said very seriously: "I don't think I can believe it all, but I can't believe it either, I should be regarded as a skeptic, right?"

Human technology has made great progress compared with the past, and it can be said that it has changed dramatically, but there are still many unsolved mysteries to be solved.

Didn't such top scientists as Newton and Einstein find that science could not explain their doubts in the later stages of their academia and study theology? ”

Brother Long was behind the two, heard their conversation, and said with a grin: "What ghosts, gods, Buddhas, and reincarnation, Lao Tzu has never believed in it, I have never seen a ghost since I lived so big!"

How can you believe something you haven't seen before? ”

Nie Tian smiled in his heart, didn't say anything, and then asked, "Sir, why do I think that this scripture has another deep meaning?" ”

The mysterious man stopped, turned to look at Nie Tian and asked, "Little brother, do you think it has something to do with this underground tower?" ”

When Nie Tian saw this opening scripture, a feeling like a call for eternity came to his heart, but this could not be known to them.

Nie Tian hurriedly covered up to the mysterious man: "That's not it, I just think there should be something else, it's not just as simple as opening the scriptures!" ”

The mysterious man smiled and said, "Brother Xiaotian, the wisdom root is extremely high, maybe you can understand something in it, and it is also related to the Buddha!" ”

The mysterious man's impression of Nie Tian is getting better and better, and he has changed from the title of Little Brother to Little Tian Brother.

Mao San followed at the end, listening to the chat between the two, he felt very irritable, and said impatiently: "Walk well, endlessly babble, and I'm not afraid that there will be a secret arrow that will shoot you through the heart!" ”

Nie Tian teased: "No wonder you have been hiding in the back all the way, you are afraid of this after making trouble for a long time!"

You're not only timid, but you don't have a brain, have you read too many tomb robbery novels, do you want to give you a big zongzi in a while, refresh! ”

The mysterious man comforted everyone: "You don't have to worry too much, although this underground tower is rare, it is not a tomb after all, although there are mechanisms set up, but it is generally not a hidden weapon." But be careful! ”

The passage was not very long, and when he was talking to the end, several people came out of the passage one after another, turned on the lights, and swept around. As the mysterious man speculated, everyone returned to the second platform from the dark passage.

Now there is no way to go down, and I am unwilling to go back, I am in a dilemma, and Brother Huo has no idea for a while. Ask the mysterious man, "Sir, do you have any idea how to go down now?" ”

The mysterious man also lost his thoughts, looked at Nie Tian, and asked, "Little brother, do you think we have something missing?" ”

Nie Tian's first reaction was the hollow of the word "曌" on the stone platform, if the hollow turned out to be a place inlaid with black fluorescent beads.

Then it is possible that the mechanism can be opened thanks to the combination of black fluorescent beads and passwords.

There is also an unknown object that I just got in the secret room.,I don't know if it's related to this mechanism.,Maybe you can try it too.。

But Nie Tian couldn't be exposed to them either, and besides, he couldn't dig his head open and take out the beads, right?

Nie Tian could only shake his head at the mysterious man and said, "Sir, you can't even think of anything, where can I do anything!" And is there sure there is another floor below this tower? ”

The mysterious man shook his head helplessly, thought for a while, as if giving Nie Tian a hint, and said: "According to the structure composed of the oval and tubular curves on the mural just now, there should indeed be another layer, in fact, the mural also reminds me of the Klein bottle, have you heard of it, little brother?" ”

Nie Tian searched his memory, but he didn't have any impression at all, and said to the mysterious man in confusion: "I haven't heard of it, what kind of bottle is it?" ”

The mysterious man hoped that after giving an explanation, Nie Tian might be able to make a new discovery, and said: "The Klein Bottle is a curved surface that can only be truly expressed in the four-dimensional space.

It is impossible to really exist in our three-dimensional space, and its structure is that there is a hole in the bottom of a bottle, which now extends the neck of the bottle and twists into the inside of the bottle, and then connects with the hole at the bottom.

Unlike the cups we usually use to drink water, this object has no "edges" and its surface does not end.

Unlike a sphere, a fly can fly directly from the inside of a bottle to the outside without having to cross the surface (i.e., it has no distinction between inside and outside).

If you have to describe its shape on the diagram, you can see the oval and tubular curves on the mural.

If you make a model in 3D space, you will go back to the original point after entering through the dark passage as we did just now.

The mural depicts two connected Klein bottles. That said, we should have a Klein bottle-shaped building layer underneath us. ”

Nie Tian was confused when he heard this, and asked puzzledly: "Sir, it's too profound, I don't really understand, so what is this Klein bottle for?" ”

The mysterious man asked himself and said, "It's just a four-dimensional space model, a topological space that cannot be oriented, but the appearance of such a structure in this underground tower is incredible."

What can it do? Guard against theft? Unlikely! And how did the ancients design this structure, is it just a coincidence? ”

Listening to the mysterious man's analysis, Nie Tiannao filled in the picture and analyzed in detail: "On the top of the two domes, there are tubular curved dark passages, extending towards their own internal arcs, passing through their respective circles, winding outward, whirling to the other top of the circle on the outside, returning to the body, passing through the intersecting circles, and finally returning to the starting point.

If this is the case, then the sphere space we are in now is obviously not just the Klein bottle structure, but according to the structure shown on the mural, it is very similar to the small circles that overlap and overlap. ”
